Our company's production facilities carry out rewinding and repair of electric motor windings of all types. This type of electric engine repair is one of the most common. During the operation of electric motors, failures on the electrical part may occur, such as interturn short circuits or wire breaks in the stator and armature windings. The reasons for such refusals are different, in particular, they may be:
- motor overload and unacceptable heating;
- prolonged exposure to vibrations;
- ingress of moisture and other liquids into the work area;
- heavy contamination of external and internal surfaces.
Manufacturing defects that appear during long-term operation of the equipment are also less common.
In such cases, it is enough to rewind the motor winding to fully restore its functionality. With the help of rewinding it is possible to repair almost all types of electric motors for general industrial and special purposes - traction, crane, elevator. It is possible to repair electric motor windings of various types of design and execution - three-phase and single-phase, direct and alternating current, synchronous and asynchronous, brushless and high-voltage, explosion-proof and explosion-proof, industrial and household.
Another common reason to rewind the winding of an electric motor (generator or transformer) is the need to change the technical operating parameters of the electric machine. For example, if it is necessary to increase the supply voltage, reduce electrical power consumption, or change the rotor speed. In such cases, we are not talking about repairs, but about modernizing the electric engine. In this case, it is necessary to recalculate the parameters of the winding units (wire cross-section, number of turns, windings, etc.).
Repair of electric motor winding
Repair of windings of electric motors or transformers is carried out, as a rule, in a specialized workshop. This requires measuring instruments, special technological equipment and, most importantly, qualified personnel. Indirect indicators for repairs are the appearance of extraneous noise during operation of the electric motor, excessive heating of the housing, loss of power, and difficulty regulating operating parameters.
Repair of electrical machine windings is carried out with copper conductors using insulating materials that are highly reliable and resistant to adverse factors. Such materials are designed for a long period of operation.
Insufficient ventilation, elevated ambient temperatures and significant loads can lead to overheating of the electric motor. Prolonged exposure to high temperatures destroys insulating materials, leading to loss of elasticity and cracking. During vibrations, the rubbing wires short out, which leads to an interturn short circuit.
It is recommended to rewind the motor winding if there are significant deviations in its operation. Repairing the windings of electric motors and generators is a more economically acceptable option. It allows you to save more than 50% of money compared to buying a new one. Restoration of windings in a specialized workshop is carried out in a short time and with a guarantee. The estimated cost of repairing and rewinding electric motors, taking into account the prices of consumables and components, is given in the price list on the website page.
